'FBUIT JAB-COVEB CLAMP.

(Be it lmown that I, "EMBRY EAs'rMAN 1'1ARDY,'=tUC ltlZGI1 of-the UnitedStat/espre- -si'dingr.at =Bayside,= in t-hevcotmty of QueensSHaind-Btate Of New iYonka'liave'i nventedueertain' new amid auseful:Improvements in Fruit- ;lanCover Clamps; of-avh-iolr theifollow-i ng 1s=a; specification.

"My invention I relates to improvements; in

Fi 7 is a fragmentary sectional view on the line w a: of Fig. 2.

'0 My improved fruit-jar cover-clamp is made of sheet material andcomprises a handle member 10 which has mounted thereon at one end a pairof clamping members, respectively an inner clamping member 11 and 5 anouter clamping member 12, the said clamping members havin each a pair ofprongs 13 for engaging with the upper portion of a fruit-jar cover 14.

The handle member 10 has near the outer 0 end a hole 15 in which ispositioned a rivet 16 for operatively holding the outer clamping member12. Inwardly from the ho 15 there is provided in the han a member 10 akey-hole slot consisting of the longi- 5 tudinally directed slot 17 onthe side remote from the hole 15, and in alinement therewith, and whichopens into the relatively enlarged portion 18 on the side adjacent thesaid hole 15.

l The portion 19 of the border wall of the enlarged portion 18 that isadjacent the straight portion 17, and on each side, is slightlyinclined. forming generally an obtuse angle with the adjacent wall ofthe said straight portion 17, and is also slightly curved, suitably toserve as a cam surface .-Specifice'tion of Letters Patent.

A rivet r205 )asses through the 1 said key rholo sloti'2l al-servesoperatively to secure =:ehe inner'elampins 'member 11 to thehandle 10.

.T heolanipinganembers 11=and 12are gen "orally-similar:anrbcomprisereach a pair of iraldial' arms v9:2, ihavingtiheiprongs1-3--atthe neuter -.ends, the said i a'rms being disposed generally= atan-- obtuse angle and being can unected ati thetjunetion at the inner-en'ds by (the. plate lik-e body 1 portion The body iportioni23isiprovided with a sliort-* slot 24 thatiis anfihfor the rivets IGandQO. The sslot 24:;extmtisllateraily across the biseeting radius.

:The: portion of the slot. 24 'oir'one side of ithmcenter only is usedat one time inclampling, fifor ruse =.in none direetion, \the portionthereof .on rthemther -side being used for vclampin'g' in the otherdirection, the-device -sbeirrg usable eeither fright f'hande'd or lefthanded.

In use, at 1 the startt-he inner clamping "member 11 is separated oropened out from the outer clamping member 12 to permit the clampingmembers being placed on the cover 14, as shown in Fig. 3, the pin 20bein positioned in the straight portion 17 o the key-hole slot 21. Therivet 20 is then pushed along the slot 17, carrying With it the innerclamping member 11, until the prongs 13 engage with the cover 14. Thenby applying a turning movement to the handle after the intermediateposition described and shown in Fig. 2 in the direction desired the pins16 and 20 slide to the ends of the cross slots 24, one on one side andthe other on the 7 other side of the axis, the clamping members 11 and12 turning accordingly, and pressure being applied to the prongs 13 dueto such movement, until at the final stage the pin 20 engages with oneof the cam surfaces 19. As the turning movement is continued, a slightmovement along the said cam surface 19 serves to effect a rigidclamping, whereby the device is securely clamped to the cover and thetightenin of the cover on the jar may be freely app ied as desired.

A reverse movement of the handle effects a release of the device.

The rivet 20 is easily moved outwardly by the thumb of the same handthat holds the handle, the final movement of the said rivet to thelocking position in engagement with the cam surface 19 being effected bythe turning movement of the handle.

The end of the handle 10 remote from the clamping .nembers is formedinto a screwdriver bit and the body portion adjacent the same as shownat 26 is provided with a square hole, suitable for use as a wrench.

I claim as my invention 1. A fruit-jar cover-clamp comprising a handlemember and a pair of clamping members, the said clamping members eachcomprising a pair of radial arms having prongs at the outer ends and abody portion at the junction of the said arms, the said body portionshaving each a cross slot, the said handle member having a hole and akey-hole slot adjacent the said hole and in alinement therewith, andmeans for operatively connecting the said clamping members with the saidhandle member comprising a pin passing through the said hole and throughthe said cross slot in one of the said clamping members and a second pinpassing through the said slot in the handle member and the cross slot inthe other of the said clamping members.

2. A fruit-jar cover-clamp comprising a. handle member and a pair ofclamping members, the said clampin members each comprising a pair ofradia arms having prongs at the outer ends and a body ortion connectingthe inner ends of the said arms, the

of prongs in spaced relation for engaging with the jar cover andconnected to the said body portion, a pair of pins serving exclusivelyof all other connecting and supporting means, through the medium of thesaid handle member, as the means for operatively supporting andconnecting the said clamping members, and being adapted to operativelyconnect the said body portions with the said handle member, the saidhandle member having a hole in which one of the said pins is fixedlysecured, and the said handle member having a transversely directed camslot for cooperating with the other of the said pins.
